[China Aluminum Network] is an AL-Mn alloy and is widely used as a rust-proof aluminum. The strength of this alloy is not high (slightly higher than that of industrial pure aluminum) and it cannot be strengthened by heat treatment. Therefore, the cold processing method is used to improve the performance. Its mechanical properties: high plasticity in the annealed state, good plasticity in semi-cold hardening, low plasticity in cold working hardening, good corrosion resistance, good weldability, poor machinability. Uses are mainly used for demanding plasticity and good weldability, low load parts working in liquid or gaseous media, such as mailboxes, petrol or lube conduits, various liquid containers, and other low load parts made by deep drawing: Wire is used to make rivets.
